there are 2 answers. You need to solve two different equations. |dw:1435066793729:dw|

i cant @peachpi
anonymous
  • anonymous
ok. let's start with the left one. There's a 10 that's subtracted. How can you cancel it out (aka move it to the other side of the equation)?
alante
  • alante
add ten with 26 @peachpi
anonymous
  • anonymous
right. so what will the equation be after that step?
alante
  • alante
2x=36 @peachpi
anonymous
  • anonymous
right, so now you need to cancel the 2 to find your x
alante
  • alante
divide 36 with the 2 @peachpi
anonymous
  • anonymous
yes
alante
  • alante
ok @peachpi the answer is 18
anonymous
  • anonymous
correct! now follow the same steps to solve the right equation
alante
  • alante
how? @peachpi
anonymous
  • anonymous
same steps you used before. Add 10 to -26 then divide by 2
alante
  • alante
divide both @peachpi
anonymous
  • anonymous
divide both sides AFTER you add the 10 to both sides
anonymous
  • anonymous
this situation is a highly chance of you becoming depressed over one question of your propaganda !
alante
  • alante
divide both side by 2 @peachpi
anonymous
  • anonymous
yes
alante
  • alante
i got 5 and 13 @peachpi
anonymous
  • anonymous
do you mean\[x-5=-13\]
anonymous
  • anonymous
I can't see what you're doing, so I'm not sure we're talking about the same equation. Can you use the draw tool to show me what you have?

When we solved the other equation we added 10 first. (see the one on the left.) Do the same thing for the equation on the right |dw:1435069181874:dw|
alante
  • alante
u get 18 @peachpi
anonymous
  • anonymous
yes. on the left equation we got 18. but there are 2 solutions. We need to solve the equation on the right. What do you get when add 10 to -26 on this|dw:1435069483961:dw|
alante
  • alante
put 18 where the x is @peachpi
anonymous
  • anonymous
2(18) - 10 = 26. That works for one answer. The absolute value equation has 2 solutions. 18 is the solution for 26. We need to find the solution for -26.
anonymous
  • anonymous
If you notice all your options have 2 numbers. Do you see what I'm saying?
alante
  • alante
@peachpi i multiplied 2 with 18 and subtracted 10 and got 26
anonymous
  • anonymous
yes that's right
anonymous
  • anonymous
that's the 18 we found above
anonymous
  • anonymous
do you understand how absolute value works?
alante
  • alante
@peachpi so whats the answer 18 and what
anonymous
  • anonymous
That's what we're solving this for. What do you get if you add 10 to -26? |dw:1435070054490:dw|
anonymous
  • anonymous
-26+10=?
alante
  • alante
-16 @peachpi
anonymous
  • anonymous
now divide by 2|dw:1435070238546:dw|
alante
  • alante
-8 @peachpi
anonymous
  • anonymous
yes
anonymous
  • anonymous
so your answers are 18 and -8
alante
  • alante
ok thank you @peachpi
anonymous
  • anonymous
you're welcome
